If a process is restarted it is assigned a new PID number but it retains its original JID number. Some processes, such as telnetd, are transient processes that are started in response to a user request (telnetting to the router). These transient processes are not managed by system manager, and their JID is derived from their processed ID (PID). For transient processes a startup file is not needed because they are not started by the system manager. System Manager and Process Lifecycle System manager monitors the health of each process.
A thread that uses round-robin scheduling runs until it voluntarily relinquishes control, gets preempted by a higher-priority thread, or consumes its timeslice. Sporadic scheduling algorithm allows a thread to run at its normal priority for a certain amount of time (budget) over a period of replenishment interval before its priority is dropped to a lower priority. Figure 2-3 illustrates how sporadic scheduling works. Threads T2 and T3 Use Round-Robin Scheduling Priority = 40 T1 is a sporadically scheduled thread with - Budget time of 20ms - Replenish interval of 50ms - Normal priority of 30 - Low priority of 10 T3 T1 Priority = 30 T1 Priority = 20 T1 T2 Priority = 10 T2 T2 T1 0ms 10ms 20ms 30ms 40ms 50ms 60ms 70ms 80ms Figure 2-3 Sporadic Scheduling Assume that at time t = 0 ms, threads T1 and T2 are ready to run and all other threads are blocked.
With this model, a database specific to a node is located on that node. info Chapter 1: Introducing Cisco IOS XR the resource. For example, Address Resolution Protocol (ARP), interface manager (IM), Bidirectional Failure Detection (BFD), adjacency manager, and Forwarding Information Base (FIB) manager are located on the line cards and are responsible only for managing resources and tables on that line card. System databases specific to the line card, such as interface-related configurations, interface states, and so on, are stored on the line card.
